// aux-build:repeat.rs

// This tests the allocating algo branch of the
// inherent impls overlap checker.
// This branch was added by PR:
// https://github.com/rust-lang/rust/pull/78317
// In this test, we repeat many impl blocks
// to trigger the allocating branch.
// Simple overlap
extern crate repeat;
struct Foo {}
repeat::repeat_with_idents!(impl Foo { fn IDENT() {} });
impl Foo { fn hello() {} } //~ERROR duplicate definitions with name `hello`
impl Foo { fn hello() {} }
// Transitive overlap
struct Foo2 {}
repeat::repeat_with_idents!(impl Foo2 { fn IDENT() {} });
impl Foo2 {
fn bar() {}
fn hello2() {} //~ERROR duplicate definitions with name `hello2`
}
impl Foo2 {
fn baz() {}
fn hello2() {}

// Slightly stronger transitive overlap
